[0029] Example one

[0030] Referring to Figure 1 The position adjusting device provided by the present embodiment includes a rotary motor 11, a driving telescopic arm 12 and a driven telescopic arm 13 arranged correspondingly;

[0031] The output shaft of the rotary motor 11 is vertically arranged in one end of the driving telescopic arm 12, and a main drive gear 14 is arranged on the circumferential side wall of the end of the driving telescopic arm 12 close to the rotary motor 11;

[0032] A sub-driven gear 15 engaged with the main drive gear 14 is arranged on the circumferential side wall of one end of the driven telescopic arm 13;

[0033] The first auxiliary telescopic arm 16 is hinged at one end away from the main driving telescopic arm 12, and the second auxiliary telescopic arm 17 is hinged at one end away from the driven telescopic arm 13;

[0034] The first auxiliary telescopic arm 16 is hinged at one end away from the main driving telescopic arm 12, and the second auxiliary telescopic arm 17 is hinged at one end away from the driven telescopic arm 13;

[0035] The first auxiliary telescopic arm 16 is hinged at one end away from the main driving telescopic arm 12, and the second auxiliary telescopic arm 17 is hinged at one end away from the driven telescopic arm 13;

[0036] Specifically, the main driving telescopic arm 12 is driven to rotate around the output shaft of the rotating motor 11 by the rotating motor 11, and the driven telescopic arm 13 rotates in the opposite direction under the meshing transmission action of the main driving gear 14 and the auxiliary driven gear 15, thereby driving the first auxiliary telescopic arm 16 and the second auxiliary telescopic arm 17 to "telescope", thereby driving the movement of the contact piece 18, and further pushing the battery.

[0037] It should be noted that the contact piece 18 can be provided with a triangular structure, one corner of which is installed at the hinge of the first auxiliary telescopic arm 16 and the second auxiliary telescopic arm 17, and in order to minimize damage to the battery when contacting the battery, the remaining two corners can be provided with rollers 19, so that the rollers 19 directly contact the side wall of the battery.

[0038] Embodiment two

[0039] Referring to Figure 2 The present embodiment provides a transfer trolley, which is provided with two position adjusting devices 1 corresponding to the positions of the two sides of the bearing surface.

[0040] Specifically, the two corresponding position adjusting devices 1 can cooperate with each other to move the battery to a certain extent, and the position adjusting device 1 can clamp the two ends of the battery to form physical limiting, effectively inhibit the battery sliding or deviation caused by the start and stop, turning or road bumping of the trolley, and guarantee the stable state of the battery during the whole transportation process, and avoid the risk of collision.

[0041] In order to further optimize the effect, referring to Figure 1The sensor 4 can be installed on the end side wall of the contact piece 18 away from the first auxiliary telescopic arm 16, and the sensor 4 is electrically connected with the rotary motor 11. Specifically, the position adjusting device 1 drives the sensor 4 to move towards the battery, when the sensor 4 detects a certain distance (such as 1 cm) from the battery, the rotary motor 11 records the angle of rotation of the rotating shaft, and then continues to move, the roller 19 fully contacts the battery side wall, and continues to push the battery to adjust the position, and after the adjustment is completed, the battery is clamped to enable the transfer trolley to move to the battery replacement cabinet position to take away the battery, and then the transfer trolley takes a new battery and returns to the bottom of the vehicle. During the movement, the position adjusting device 1 can correspondingly clamp the two ends of the new battery, and after reaching the position, the rotary motor 11 can be rotated to the recorded rotation angle according to the recorded rotation angle of the rotary motor 11, so as to push the new battery to change the position and restore the position of the original battery, so as to facilitate the reinstallation of the new battery into the vehicle.

[0042] It should be noted that, as shown in Figure 2 The transfer trolley bearing surface is provided with a sensing device 5 for sensing the position of the driving telescopic arm 12 or the driven telescopic arm 13. Specifically, the sensing device 5 is provided with four, one sensing device 5 corresponds to one driving telescopic arm 12 (or driven telescopic arm 13) to determine whether the driving telescopic arm 12 (or driven telescopic arm 13) is reset and whether the reset is in place.

[0043] It should be noted that the position adjusting device 1 can be installed on the bearing surface of the transfer trolley in the following way:

[0044] The rotary motor 11 is installed at the bottom of the transfer trolley bearing surface, and the remaining parts of the position adjusting device 1 are located at the top of the bearing surface. The rotating shaft of the rotary motor 11 penetrates the transfer trolley bearing surface to connect the driving telescopic arm 12. The remaining parts are installed according to the installation method of embodiment one. One rotating shaft 2 is vertically connected to the bottom of one end of the driven telescopic arm 13 which is sleeved with a driven gear 15. An outer bearing 3 is sleeved on the rotating shaft 2, and the outer ring of the bearing 3 is clamped in the inside of the transfer trolley bearing surface. Thus, the installation of the entire position adjusting device 1 is realized. Of course, the position adjusting device 1 can also be installed on the bearing surface of the transfer trolley in other ways, as long as it can normally operate.

[0045] In this paper, specific examples are used to illustrate the principles and implementation methods of the present application. The above examples are only used to help understand the method and its core idea. Meanwhile, for those skilled in the art, according to the idea of the present application, the specific implementation and application range will be changed. In summary, the content of this specification should not be understood as a limitation of the present application.
